Selecting Fasteners And Power Loads - Remington Powerdriver 490 Instrucciones De Operación

FASTENING INTO CONCRETE
The proper power fastener length
can be determined by adding the
thickness of the material to be fas-
tened and the amount of power
fastener that will actually penetrate
the concrete. The concrete must
be three times as thick as the in-
tended power fastener penetra-
tion. In most cases, penetration
should be approximately 1" to 1
into the base concrete material.
FASTENING INTO STEEL
The proper power fastener length
can be determined by adding the
thickness of the material to be fas-
tened and the thickness of the steel.
The point of the power fastener must
go completely through the steel.
POWER LOADS
Always start with the lowest power
level (gray-level 1). If the first test
power fastener does not penetrate to
the desired depth, move to the next
highest power level (brown-level 2).
Increase until a proper fastening is
made. IMPORTANT: Damage to
the tool will result if the above instruc-
tions are not followed (see illustra-
tions to right and lower right).
OVERDRIVEN POWER
FASTENERS AND PISTON
An overdriven power fastener re-
sults when too strong of a power
load is used causing the piston to
extend past the muzzle. Move to the
next lightest power load. Repeated
overdrive will damage your tool. By
avoiding overdrive, you can extend
the life of your tool considerably.
NOTE: NEVER fire the tool without
a power fastener. This can damage
the tool and/or cause possible in-
jury to the operator.
IMPORTANT: DO NOT use power fasteners longer than 2
or power washer fasteners longer than 3". Power fasteners
1
longer than 2
cause load ejection problems.
